HDBaseT Receptacle Connector Lid Switch Link Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In HDBaseT communication systems, determining the presence or absence of a communication link between apparatuses is challenging due to the state of partner apparatuses, especially when power supply is cut off or in deep standby modes, leading to difficulties in maintaining efficient power consumption and communication.
Innovation Solution
A receptacle connector conforming to the HDBaseT standard, featuring a lid that opens and closes to maintain a half-open state when a plug is inserted, and a switch that changes states with the lid, allowing for accurate detection of plug insertion and communication link presence, with an optional spring for ensuring lid closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication link detection is performed using communication data in HDBaseT standard, then communication can be maintained, but it becomes difficult to determine presence or absence of communication link when partner apparatus is in deep standby mode
Solution Approach 1:
The patent introduces a switch as an intermediary component that directly detects plug insertion state and generates switch data. This switch acts as a mediator between the physical connection state and the communication system, providing reliable detection information regardless of the partner apparatus's power state. The switch data serves as intermediate evidence that confirms actual connection status independently of communication data.
Solution Approach 2:
The patent performs plug insertion detection via the switch before attempting communication link establishment. By detecting the physical connection state in advance through the switch, the system can prepare appropriate communication protocols and power management strategies beforehand, ensuring reliable operation even when the partner apparatus transitions to deep standby mode.
2Object-affected harmful factors
If lid is designed to fully close the insertion port, then protection is improved, but user burden and occupied space increase
Solution Approach 1:
The patent implements a lid that closes partially rather than fully, covering only the essential portions of the insertion port that require protection. This partial closure provides sufficient protection against dust and contaminants while leaving enough opening for easy plug insertion and removal, reducing user burden without significantly compromising protection.
Solution Approach 2:
The lid is designed as a separate movable component that can be independently opened and closed. This segmentation allows the lid to provide protection when needed while being easily movable for plug access, balancing protection and ease of operation through functional separation.
3Reliability
If spring is added to apply force to close the lid, then lid closure reliability is improved, but device complexity increases
Solution Approach 1:
The spring mechanism enables the lid to automatically return to its closed position without user intervention. Once the lid is opened for plug insertion, the spring stores energy and automatically closes the lid when released, providing self-service functionality that improves closure reliability without requiring additional control systems or increasing overall device complexity significantly.

AI summary
A receptacle connector includes a receptacle including an insertion port into which a plug is inserted, a lid configured to open and close the insertion port and maintain, while the plug is inserted into the insertion port, a state in which the lid is opened by the plug, and a switch configured to change over according to the opening and closing of the lid.
